Assess and eliminate

It may be tempting to dump the entire contents of your vanity into your bag and jet, but resist that urge. Instead, consider how long you will be away, what you'll be doing on your trip, and what beauty products you truly need. Overnight visit? Skip your weekly face mask. A weekend getaway in the country? Leave the red lipstick and metallic eyeliner at home.

Rely on multitaskers

Bring less by choosing products that work double (or triple) duty. Streamline your skin care routine with Clinique Smart Custom-Repair Serum, which offers the benefits of multiple antiaging treatments in one bottle. A powerful blend of youth boosters work to combat the issues specific to your complexion—from wrinkles to spots to dullness. Plus, the hydrating, soothing formula calms travel-induced skin irritation. For your hair, pick up a cleansing conditioner, which simultaneously suds and softens. One to try: Pureology Travel Size Hydrate Cleansing Conditioner.

Switch to solids

No crying over spilled beauty products: Avoid leaks in your suitcase by opting for solid formulas whenever possible. A few spill-proof options to scoop up: wax-based perfumes, lotion wipes, and stick suncreens (try Clinique Broad Spectrum SPF 45 Sunscreen Targeted Protection Stick).

Limit liquids

Decant any leftover liquid products into clear, three-fluid-ounce bottles; the TSA-approved size ensures you won't get held up at security. Just be sure to label each one so that you don't accidentally wash your face with shampoo! If you don't use the entire bottle while you're away, top it off when you get home and keep it at the ready for future trips.

Be size-smart

Stash your travel-friendly arsenal of products in a clear zip-top cosmetics case. It's ideal for quickly finding and accessing what you need, and is easy to clean in the event of an unexpected spill. If you're not checking your suitcase, keep in mind that this bag has to be quart-size or smaller. One that fits the bill: Stephanie Johnson Small Zip Cosmetic Bag.
